Hi All
At first I thought it is easy to find those tables to use
sequences but I failed. dba_sequence don't give too
much info. Is there any idea?
Thanks in advance

no table "uses" a sequence. And there is no reason (other than sanity
checks) to have one sequence per table.
SQL code will use the sequence, usually to retrieve a value from the
sequence to then insert into or update a column in a table.

Michell,
A sequence is created and select privileges granted to users or roles.
The users or roles use the sequence in the applications to insert/update
the data in the tables. Check the privileges granted to the users/roles
and then get the info from the developers as to which tables use the
sequ
Well, there could be business logic reasons as to why you would have one
sequence per table.
Also, I don't know if I would ever go with one sequence for many tables,
sounds like a bottle neck to me. And how would one sequence for many tables
impact scalability?? Or having lots of users hammerin
If you are using the sequence to generate the primary key for a table, then the
sequence should only be used for that table. I can't think of a pro to have one
sequence shared for the primary keys on many different tables.

I didn't say you should have only one sequence in the database. I said
there was no reason you had to have multiple ones.
and there isn't. There is no restriction in Oracle that you have to do
so. As it happens, for many of the reasons you stated, we have multiple
sequences. That is, where I can g

I'd check dependencies of the sequence, you'll know what procedures,functions,packages,triggers that sue the sequence.

In order for sequence not to become a "bottle neck", use "cache" option.

A mad rampage through DBA_SOURCE might reveal something useful.
Something like:
select name,text from dba_source where upper(text) like '%SEQUENCE_NAME%';
And do the same with TRIGGER_BODY from DBA_TRIGGERS.

there is no way to know for certain which sequence is being used to
generate values for which table. Even if you have multiple sequences,
you can't force a programmer to use the sequence you have designated as
"the one" for th
In addition to what Jacques has mentioned, here is my 0.02.
Why only one sequence per table? Does it stem from the concern that a single
sequence becomes "overloaded" with request to be inserted into multiple
tables?
The overloading does not come from number of tables, but number of
